Abstract
A sander for finish working the peripheral edge of a workpiece includes a power driven workpiece carrying member which is moved in a horizontal plane and supports the workpiece so that the workpiece moves with the workpiece carrying member. The workpiece carrying member moves with rotational and translation motion in a horizontal plane. An endless sanding belt is located adjacent to the workpiece carrying member with one belt flight located adjacent the workpiece carrying member and, thus, the peripheral edge of the workpiece. A workpiece edge contouring head is located to the back side of the sanding belt at a location along the belt flight which is adjacent the peripheral edge of the workpiece and is biased to force the sanding belt against the peripheral edge of the workpiece. The sanding belt and contouring head are mounted for conjoint pivotal movement about a common pivot.
